Many thanks to those of you who have expressed concern about my dad. His health is declining and we are in a day-to-day mode. My brother lives in Richmond near him and is bearing most of the load, and I will be going back and forth as the situation changes. My dad's assisted living center staff is absolutely fantastic and it is very comforting to know that he is loved and cared for there. I am planning another Smokies trip soon if we feel that things are stable enough. Keep checking in!
